Abstract: Embodiments of this application disclose a rule detection method, to increase rule anomaly detection coverage. The method in the embodiments of this application includes: determining, based on an obtained first initial priority corresponding to a first rule, an obtained second current priority corresponding to a second rule, and a determined inclusion relationship between the first rule and the second rule, a first current priority corresponding to the first rule; and then determining, based on a relationship between the first initial priority and the first current priority, whether an anomaly occurs on the first rule.

Abstract: Embodiments of this application disclose a traffic monitoring method, an apparatus, an integrated circuit, a network device, and a network system. When receiving a first packet, a traffic collection apparatus determines that a measurement value of a target performance indicator of the first packet matches a value of first information in a first register, updates a value of second information in the first register based on the measurement value of the target performance indicator of the first packet, and increases a value of third information in the first register by 1.

Abstract: Embodiments of this application disclose a traffic monitoring method and apparatus, an integrated circuit, and a network device. When the traffic monitoring apparatus receives a packet, after determining that the traffic monitoring apparatus includes an empty first register, the traffic monitoring apparatus updates a value of first information in the first register to a measured value of a target performance indicator of the packet, and increases a value of second information in the first register by 1. The value of the second information in the first register is 0, the first information in the first register indicates a depth of a data bucket that carries a measured value of the target performance indicator of a to-be-monitored packet, and the second information in the first register indicates a quantity of packets that are in received packets and that match the value of the first information in the first register.
